Intelligent plug-in circuit breaker and its monitoring and early warning system

Abstract

The invention provides an intelligent plug-in circuit breaker and its monitoring and early warning system, which is composed of a plug-in circuit breaker, a monitoring and early warning device, a portable terminal and a monitoring center server. The monitoring and early warning device includes a measurement and control module, a temperature acquisition module, a voltage and current acquisition module, a communication module, a display module and an audible and visual alarm module. By measuring the real-time temperature of each contact, measuring and calculating various electrical parameters, comprehensively analyzing and judging the working status of the plug-in circuit breaker, especially analyzing and judging its unhealthy or abnormal status, so as to realize early warning. In addition, the temperature alarm and temperature protection functions are realized. The plug-in circuit breaker is highly integrated with the monitoring and early warning device, with simple structure, convenient installation, safety and reliability. The transformation is easy to implement, which effectively reduces the failure rate and damage rate of equipment and improves the reliability of power supply.

Description

Technical field [0001] The invention relates to an intelligent plug-in type circuit breaker and its monitoring and early warning system, in particular to an intelligent plug-in type circuit breaker with contact temperature protection, early warning and operating parameter record analysis and its intelligent monitoring and early warning system. It belongs to the field of intelligent electrical equipment. Background technique [0002] At present, the circuit breaker does not have an integrated intelligent electrical parameter measurement device. To solve this problem, a general electrical parameter measurement instrument is usually combined with it temporarily. Often, it cannot be installed because there is no reserved space, or the installation space can only be installed. A single-function instrument, and basically does not have operating data recording and analysis functions. [0003] The traditional plug-in circuit breaker has a single function and does not have an integrated mo...

AI Technical Summary

Problems solved by technology

At present, there is no intelligent plug-in circuit breaker system

[0005] In addition, in terms of safety in use, because the circuit breaker passes a large load current for a long time, the plug-in contacts are prone to overheating, and the contact parts of the contacts are affected by thermal oxidation or mechanical deformation, forming a vicious circle, resulting in contact failures. Problems such as overheating and burning occur from time to time. At present, the protection of the power system is aimed at the line and the electrical equipment connected to it, not directly at the circuit breaker body. Field operations often cause power outages due to short-circuiter contact failures. Therefore, It is necessary to monitor, protect and state early warning of overheating of circuit breaker contacts

At present, there are no relevant patents and technologies for the intelligent monitoring and early warning system for plug-in circuit breaker contact temperature protection, early warning and operation parameter record analysis
